Jay Balunas commented on RF-7538:
---------------------------------

In the 4.0.X timeframe I would like to see this type of behavior accomplished using the behavior framework if JSF 2.0.  Where you can do something like this.

The name is just a first pass

<a4j:commandButton ...>
    <a4j:enableBehavior .... />
</a4j:commandButton>

When ready to implement we will need to create a wiki page and design/discuss.

> The submit button is not enabled until all the required fields within the form/region are set properly. 
> I can think of two ways to implement it.
> 1) add a new attribute to a4j:form/a4j:rigion to indicate that if this feature is turned on/off. In addition, new attributes could be added to indicate the ids of the submit  button, and/or ids of the required fields.
> For example: 
>  <a4j:form id="myForm" enableSubmitButtonForRequriedFields="true" submitButtonId="btnId" requiredFieldIds="id1,id2..." />
> 2) add a new attribute to a a4j:commandButton to indicate if this feature is turned on/off. In addtion, new attributes could be added to indicate the ids of the form/region and/or the ids of the required fields.
> For example:
>  <a4j:commandButton id="btnId" enableSubmitButtonForRequriedFields="true" parentidforrequiredfields="myForm" />
> The example showed above means after all the required fields are set properly with the form "myForm" the button is enable.
>  <a4j:commandButton id="btnId" enableSubmitButtonForRequriedFields="true" requiredFieldIds="id1, id2..." />
> The example showed above means after all the required fields specified by the attribute "requiredFieldIds" are set properly the button is enabled.
> Of course, the attribute "enableSubmitButtonForRequriedFields" could be optional. So only the "parentidforrequiredfields" or "requiredFieldIds" is checked to determine if the button needs to be enabled/disable.
